consider option to ignore key lookup in occ_download()

[jhnwllr]

I think it would be nice to allow users who know what they are doing to ignore the key lookup.

By "ignore lookup" do you mean adding non-key fields to the predicates (e.g. kingdom, phylum, class, order, family, genus, subgenus, and species)?

Just allow users to bypass the lookup if they know what they are doing, so I don't have to always add new terms to the dictionary. Something like ignore_key_lookup=TRUE. The default would be FALSE.

[dmi3kno]

They would need to write in ALL_CAPS then, right?

I was thinking something like this...

occ_download(pred("new_key_not_in_look_up",123232),ignore_key_lookup=TRUE)
